Industrial Minerals - Ball Clay

Ball Clay (or plastic clays), is a kaolinitic mineral clay and a member of the phyllosilicate group of minerals. It occurs generally as an aluminium silicate comprising weathered forms of quartz, mica and kaolinite. Although similar in chemical composition, BALL CLAY is not as common as kaolin and differs substantially in physical characteristics.

Ball Clay - Digitalfire

Ball clays tend to be quite refractory (PCE 28-34) and some less processed deposits are sold as fireclays. Ball clay is not a clay mineral in itself, but contains other minerals, primarily kaolinite (but also montmorillonite, halloysite, and illite). Mica and quartz are also present in substantial amounts (e.g. 10-20% for Tennessee ball clays).

Chemistry of Pottery Clays Actforlibraries

The chemical composition of clay is permanently altered by firing. Firing may take place in an oxygen atmosphere, or in reduction. This will affect the color of the glazes or the clay by affecting the chemical compounds at the surface. Iron, for example, tints ceramics the familiar terra cotta color of roof tiles if fired at a low temperature ...

20. MINERALOGY AND CHEMICAL COMPOSITION OF CLAY

Clay minerals are very small, usually less than 4 µm in diameter, and have net negative sur-face charge (Brindley and Brown, 1980). Their high surface area and negative charge, providing large reaction surface and ion-exchange capacity, allow clay minerals to track relatively subtle changes in flu-id chemical composition.

What is the chemical composition of clay?

What is the chemical composition of clay? Its composition is (K,H3O) (Al,Mg,Fe)2 (Si,Al)4O10 [ (OH)2, (H2O)]. Illite has an absence of swelling due to its tightly interlaced molecular spacing. It is a common mineral found in sediments, soils, and metamorphic rock. Click to see full answer.

Introduction to Glaze Composition

BALL CLAY is a commonly used clay in glazes and in clay bodies, and is a source of SILICA and ALUMINA. KAOLIN is another commonly used clay, very white in color, used in glazes and in the formulation of Porcelain clays in particular. FELDSPAR is probably the single most commonly used glaze ingredient. It is a natural mineral, derived for granite.
